Answer:
Nanotechnology has bring up major advances in our everyday life. For example, the use of Nanobots that are extensively used now a days in medicine to make surgeries faster and accurate. By the use of nanotechnology, major problems like cancer can be treated by using cell by cell therapy. It is also utilized in curing genetic defects. Major drug designing and drug delivery has been made easier using nanotechnology.
Nanotechnology doesn't have any visible disadvantages but there always remains a fear like introduction of some extra contaminants and toxins in the environment. But mostly i agree with use of nanotechnology for the betterment. Furthermore we don't have any more advance techniques to fight problems than this technology.
<span>A. abiotic component</span>
An ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. Every animal, plant and human needs the primary physiological needs of water, food and shelter provided by the abiotic system.
The presence of a fever is usually related to stimulation of the body's immune response. Fever can support the immune system's attempt to gain advantage over infectious agents, such as viruses and bacteria, and it makes the body less favorable as a host for replicating viruses and bacteria, which are temperature sensitive. Infectious agents are not the only causes of fever, however. Amphetamine abuse and alcohol withdrawal can both elicit high temperatures, for example. And environmental fevers--such as those associated with heat stroke and related illnesses--can also occur.
The hypothalamus, which sits at the base of the brain, acts as the body's thermostat. It is triggered by floating biochemical substances called pyrogens, which flow from sites where the immune system has identified potential trouble to the hypothalamus via the bloodstream. Some pyrogens are produced by body tissue; many pathogens also produce pyrogens. When the hypothalamus detects them, it tells the body to generate and retain more heat, thus producing a fever. Children typically get higher and quicker fevers, reflecting the effects of the pyrogens upon an inexperienced immune system.
The answer is identical to the original body cell or it is half of the original body cell.
A cell cannot live forever so they either divide into two new cells through mitosis or die.In the process of mitosis <span>one cell divides into two identical cells. So, a genetic material in the nucleus of each of the new cells will be identical to the original body cell.
</span>Beside mitosis, there is meiosis. It i<span>s a cell division that results in the reduction of chromosome number by half. In this case, new cells will be haploid and there will be half less genetic material than it the original body cell.</span>
